听力题 M: I have recently read a book on signals and words. I learned a lot about signals used in conversation. W: It sounds quite interesting. What have you learned about that? M: It says that with the development of behavioral sciences, researchers find that the importance of speech has been overestimated. W: How interesting! I only know that speech is quite important in communication. M: It''s true. But it''s not the only means of communication. Maybe it''s the most conscious way in communication. W: Then, what other means can we use to communicate? M: Well, it is possible that we are unconsciously sending out messages with our every action. Sometimes we unconsciously pick up others'' messages, and we even form opinions based on such messages. That''s probably an explanation of some people "love at first sight", and sometimes we just have to make "snap judgment." W: Yes, you mean we communicate a lot with our bodies, we send out messages when we move, sit, stand and whatever we do with our hands and our heads. M: That''s absolutely correct. Just imagine a few people sitting in a waiting room. One is drumming his fingers on his briefcase, another keeps rubbing his hands together, another is biting his fingernails, still another grasps the arms of his chair tightly and a final one keeps running his fingers over his hair. W: Excellent examples! These people actually aren''t talking, but they are "saying" a lot if we happen to know the "language" they are using. M: Right, I can''t agree with you more. There are also two most "telling" forms of behavior. One is driving a car. The other is playing games such as card games or chess. It is interesting to note a person''s reaction to stress in these situations and aggressive behavior in others. W: If he easily becomes angry, excited, passive or resentful when driving or playing, we may have a clue to his personality. M: Yes, I''m sure we will. Oh here comes the bus. Let''s be quick. Our language class is about to begin in fifteen minutes. W: Yes. We also can discuss this interesting topic again with Professor Lee.
